ApplicationAugust 11, 1934, Serial No. 739,461 teams, (01.210-121) This invention relates to improvements in filteringdevices and pertains particularly to a device for filtering liquids. L r The primary object of the present invention is to provide an improved liquid filter which, while intended for any use to which it may be applica- Me, is primarily designed for the filtering of wine so that the latter, after being passed through the filter, will be free of all sediment and in a clear and sparkling condition.

Another object of the invention'isto provide a filter having a novel arrangement of parts whereby the filter may be readily taken apart. for cleaning when such procedure is necessary.

The invention will'be' best understood from a consideration of the following detailed descrip tion taken in connection with the accompanying drawings forming part-of this specification, with theunderstanding, however, that the invention is not confined to any strict conformity with the showing of the drawings but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claiin's; I

In the drawings:

Figure'l is a view in side elevation of the filter embodying the present invention, portions being in section.

Figure 2 is a vertical sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a horizontal section taken on the line 3-3 of Figure 1.

Figure 4 is a detailed view of a strainer of a filter.

Figure 5 is a. sectional view taken on the line 5-5 of Figure 1.

Figure 6 is a view of a portion of the under side of the filter top.

Referring to the drawings wherein like numerals of reference designate corresponding parts throughout the views, the numeral I indicates the outside body or shell of the present filtering device which is preferably in the form of the lower half of a barrel so that the wall is bowed outwardly and the top opening 2 is of greater diameter than the interior of the bottom.3. Disposed within the body I is a tapered cylindrical strainer unit which is perforated throughout, as indicated at 5. This strainer 4 is reinforced at its top and bottom and also intermediate its ends, by the reinforcing metallic bands 6, and as is illustrated, the narrower lower end of the strainer 4 rests upon the bottom 3 of the body I and is of substantially 4, which is preferably of metal and the same'ov'erall diameter as the bottom at the inside' of the 'body while the upper end of the strainer is of an overall diameter to snugly fit in the top opening or mouth of the body.

It will also be apparent that since the wall of the strainerlis straight throughout, a relatively wide area remains between'the same and the wall of the body I, and into this area, the liquid to be filtered is discharged through the pipe connection l which is arranged in its outer end for the convenient connection of a hose therewith while the inner end, which opens through the wall of'the body I is covered upon the interior of the body by the relatively wide strainer 8. of a diameter materially greater than the-inlet end of the pipenipplel so that the least amount of resistancefto the entrance of the liquid is offered.

The bottom 3 of the body i has, an opening through whicha section 'of pipe 9' extends, which pipe section constitutes the outlet for the filter. The inner end of the pipe section 8 projects a substantial distance above the bottom} and is screw threadedto receive the coupling It. Disposed centrally within the strainer 1 is a cylinder II which has the downwardly extending conical botto mfwa ll' ligand the flat top wall" I3. These "walls, as well as the side wall of the cylinder, are

perforated throughout and the interior of the cylinder is provided with suitable reinforcing bands I4 to prevent its collapse under the pressure which is applied thereto.

Extending centrally through the cylinder II is a perforated tube l5, which has its upper end in contact with the upper end wall I3 of the cylinder, while its lower end passes through the center of the lower wall of the cylinder and is threaded for engagement by the coupling collar I0 by which it is held in alinement with the pipe section 9. This perforated tube l5 has its perforations lying only within the confines of the cylinder H, that portion of the tube I5 which extends beyond the bottom wall I2 of the cylinder being unperforated.

The upper end of the body I is closed by the relatively heavy head I6 which is provided in one The strainer 3 is p face with the annular channel I! in which a rub- I. Two of these straps are formed integral with one another and connected across the bottom of the body I, as indicated at 22a, thus providing a reinforcing means for the bottom of the filter, and a suitable aperture is made in the reinforcing band for the extension of the outlet pipe 9 therethrough. The upper ends of the bolts 20 are 'screw threaded to receive the winged nuts 23 which bear against suitable washers placed upon the top of the head I6. soas to clamp the head firmly in position. It will thus be seen that when the head is in place, it will bear against the upper end of the straining cylinder 4 and secure the latter firmly in position.

The inner straining cylinder I I is encasedinr' bags being drawn in and tied beneath the cylinder II about the lower imperforate end of the tube I5.

Whenthe filter is to be used, the straining cylinder 4 is packed With asuitable filter material such as filter paper so-that the inner cylinder II and the encasing bag or bags 24-thereforwill'be entirely encased in this filtering material, After the filtering material has been placed in the straining cylinder 4, the head I6 is replacedand theliquid. to be strained or filtered is forced by any suitable means through theinlet strainer 8-and caused to pass through the filtering materiaL the bag 24, and into the cylinder I I topass out through. the tube I5 and the outlet pipe 9.

For the purpose of flushing thefiltering material, and also to let any fluidvv drained. off, when the filtering material is being packed, into the cylinder 4, as, the material is preferably packed in while in dampened. position, an outlet pipe 25 is connected through the wall of the body I in the lower part of the latter and this is normally closed by the removable cap 26 which is, ofv course,

removed while the packing of thefilter. materialis taking place and also while the filter is being flushed.

What is claiinedisz- 1. A filter, comprising abarrel body having a wall curvedto-form a continuousoutward bow from top to bottom and having an open top of slightly greater diameter than the bottom, a

tapered receptacle adapted to position in the body upon the bottom thereof, the overall diameter of the smaller end of said receptacle being substantially the same as the interior diameter of said body at the bottom and the overall diameter of the top of 'the receptacle being substantially the same as the interior diameter of said top and the top edge, of the receptacle being flush with the top edge of the body, a cover disposed upon the top of said body and engaging the same and the receptacle to maintain the latter in position, means for drawing said cover tightly against said body and receptacle, a filtering material within the receptacle, the receptacle being of a perforate character, fluid inlet means opening throughthe wall of the body, an outlet tube secured to the bottom of the body and extending into the filtering material of the receptacle, a perforate: receptacle mounted upon said outlet." tube and' in', communication with the same, and a substantially bag like. strainer enclosing said' last perforate receptacle having a mouth drawn in aroundithe-outlet tube.

2. In a filter structure, a body of barrel-like form having a. bottom and an open top of a diameter greater'than the bottom, a straight walled cylindrical receptacle having top and bottom diameters substantially the same as the top and bottom inside diameters of said body and of the same inside height as: the body and positioned therein, said wall being perforated, a straining outlet means forthe body, a top for the body carrying sealing means engaging the.

topedges of the body andof the receptacle, fluid inlet means for the body adjacent the transverse center: of the same, a: plurality of straps secured vertically to the outside of the body and each terminating at its top end in a hinged portion, two opposite onesof the straps being joined by a reinforcing strap passingbeneath the body, and securing. elements adapted for detachable connection with said top and each hingedly coupled with one of said strap hinge sections.
